If you've got a query about a thread deletion, you know where to post it! (Ask the Community Team in case you didn't know)

Making a thread about a thread being deleted is only a surefire way to get it, well, deleted! The reason for us not allowing people to discuss this in public is that often this kind of thing has many underlying factors that cannot be disclosed publicly, or ultimately we removed it from the site for a reason.

The community won't know why it got deleted, or may not be aware of the guidelines that the thread broke, so having it open to public discussion isn't really that helpful for anybody.
